reliability mathematics
1.7. Four strength failure modes of gear are analysed, and the respective reliability designing mathematics models of these modes are established accordingly.
2.Abstract: Abstract：Reliability models are reliability block diagram and mathematics models that built to predict and evaluate reliability of products. Several system reliability models and their calculational methods are introduced.
3.Let the inherent frequency, frequency of excitation force, vibration response of mechanical parts be processed according to reality into random variables, by means of combining relevant optimization technique, reliability theory and fuzzy mathematics into an organic whole, and taking the traditional vibration designing method as a foundation, the fuzzy optimization designing method on machinery components based on reliability was put forward.
4.Based on the analysis of the breakdown of the main propulsion apparatus and the reliable mathematics model, this paper analyses and judges the reliability of the main propulsion apparatus by FTA and FCE. Meanwhile on the current device and technology, this paper also discusses the technical measures of improving the main propulsion apparatus of small and middle size ships by practice.
